Nested functions often do not need trampolines, they just need an environment pointer (the static chain). Trampolines are only needed if you pass around the address of a nested function, and it needs one of its parents frames, and your function pointers do not hold space for an environment pointer already. Trampolines do not need an executable stack, it's just the traditional way to implement them (and a very convenient and on most archs very efficient way). Segher
